Data integration method of 3-dimensional scanner and system using same

Abstract

According to the present disclosure, partial precision shape data is added to overall data by combining scan data obtained by a first scanner and a second scanner, respectively, and thus, missing data in a scan of the first scanner is supplemented by a scan of the second scanner. There is an advantage of being able to derive highly reliable data through such a supplementary process, and a user can provide a more suitable treatment to the patient.

 a first scan operation of scanning a subject through a first scanner;   a modeling operation of forming a 3-dimensional model of the subject based on data acquired in the first scan operation by a calculating unit;   a second scan operation of scanning a specific area of the subject corresponding to a supplementary area requiring an additional scan in the 3-dimensional model through the second scanner; and   a supplementing operation of supplementing the supplementary area based on data acquired in the second scan operation by the calculating unit.   
     
     
         11 . The method of  claim 10 ,

         12 . The method of  claim 10 ,
 wherein the first scan operation scans the entire shape of the subject at a preset capturing angle and capturing distance, and the second scan operation scans a partial shape of the subject at a free capturing angle and capturing distance.
